IEEE PC37.60/Cor1/D2

IEEE PC37.60/Cor1/D2 is an approved IEEE draft corrigendum for the requirements governing overhead, pad mounted, dry vault, and submersible automatic circuit reclosers and fault interrupters used on alternating current systems up to 38 kV. It is relevant to power and energy engineering because it helps correct and refine the technical requirements that support safer equipment selection, clearer specifications, and more consistent compliance work for medium-voltage distribution applications.

What is IEEE PC37.60/Cor1/D2?

This technical document serves as Corrigendum 1 to the IEEE standard covering automatic circuit reclosers and fault interrupters for AC systems up to 38 kV. In practice, IEEE PC37.60/Cor1/D2 is used to amend or clarify requirements tied to equipment design, ratings, construction, and performance expectations. It is aimed at maintaining alignment in the standard’s language so manufacturers, engineers, and reviewers can rely on a more consistent basis for evaluation and documentation.

Where is IEEE PC37.60/Cor1/D2 used?

This corrigendum is most relevant in utility and distribution environments where automatic circuit reclosers and fault interrupters are specified for overhead lines, pad mounted installations, dry vaults, and submersible configurations. IEEE PC37.60/Cor1/D2 may be consulted during equipment engineering, procurement, testing, and specification review for medium-voltage systems up to 38 kV. It is especially useful where installation conditions differ and the equipment must match the intended enclosure, mounting method, and operating environment.

Why is IEEE PC37.60/Cor1/D2 important?

For teams working with distribution protection equipment, IEEE PC37.60/Cor1/D2 helps reduce ambiguity in the governing requirements and supports more consistent compliance decisions. That matters when comparing products, verifying test results, or preparing technical submittals for reclosers and fault interrupters. By clarifying the standard’s requirements, the corrigendum can help improve specification accuracy, support safer application, and lower the risk of mismatched expectations between suppliers, engineers, and operators.
